WebGluconeogenesis is a metabolic mechanism in which the liver synthesizes glucose from substances other than carbohydrates, such as lactate, glycerol, and amino acids. During the fed state, glucose levels in the blood are elevated, and insulin is secreted to increase carbohydrate storage as glycogen in the liver and muscles. WebFollowing secretion, glucagon travels to the liver, where it stimulates glycogenolysis. The vast majority of glucose that is released from glycogen comes from glucose-1-phosphate, which is formed when the enzyme glycogen phosphorylase catalyzes the breakdown of the glycogen polymer.
